How to read changing file contents

[tomkonikkara]

The method both of you described to find the change in file may be correct. But actually that isn't my problem.
call readAll()
a change is made in the file externally.
call readAll()
in both calls, i am getting same result. That means, the change is not seen on the output.

Close the file, then reopen it, or create a new QTextStream each time you want to read it. QTextStream caches the file contents on the first readAll(), so when you ask for it again, you get the same thing. You could try calling seek( 0 ), but that still might not empty the cache.
